looool new here and dont know how to use it yet , I've just done the belt on my jts and worked a few thing's out but I posted it in NEWBI INTRO , if your doing your belt check it out it will help , beleive me I'm much better with engineering than extremley clever stupid PC's loool , Nee

elo Mitch , engine's purring mate if the camb's dont move why do you need lock's ? it's an urban myth that a lot of people who dont fix their own car's get told to get charged for part's they dont need as far as I'm concerned ,lmfao it did start with a f*kn massive cloud of smoke tho , the last thing I was expecting but buy the time the follower's had filled up it cleared , think I had the engine on it's side with oil still in at some point lol , jus keep sayin the alfa mantra "remember it's an alfa" apy motorin mate , Nee.

Fair enugh fella but seriously i've worked on all kind's of engine's fa 30 yrs + load's of them want u t use tool's as the camb's are under pressure from valve terain at tdc + wil move some but the jts has no resistance at all at tdc , i checked it on the dead lump that came out , same goe's for most tensioner tool's esentialy the tool make's up for another pair of hand's .

How do you know they were right to start with ????

It don't take much for the pistons and valves to touch .. might not do it straight way, but give it a few weeks and the belts start to stretch a minute amount ...

I alway's retension after 1k or so for the stretch even though modern tensioners are made to cover the movement,i like my engines right or whats the point lol , it's nothin to take the covers of + reasuring to take a look , Nee .

Yes, but the point is that the cam pulleys are not pegged to the camshafts. The Alfa procedure is to time the engine more accurately by locking everything and allowing the cam pulleys to rotate. That way, the timing is more accurate than to doing it to the nearest tooth on the belt. Without using the locking tools you are relying that the person doing the job before got the cams in the correct position. Your engine is not right as you have not followed the correct procedure.

Read ful post , I checked everything on the dead engine including pulley to camb float ,which there was none on inlet unless forcibly moved , if the pulley moved easily in relation to the camb you would use a tool to lock the 2 together or mark accordingly and it's a 2 man job . I've been working on variable valve terrain engines since they came out .

The exhaust camb is direct to pulley ' locked ' only the inlet moves and only at certain rpm through the variator which is an oil pressure operated servo .

I've tried to keep out of this because this has all been covered on here MANY times.

Have you actually looked at the correct procedure?
I'm guessing you haven't.
The cam pulleys should be loose when the belt is tensioned (with the cams locked with the correct cam locks). Only after the belt is tensioned are the locks removed and the pulleys tightened.
